More module problems. This time it only showed up in the stage 2 compile of clang-x86_64-linux-selfhost-modules-2 but not the stage 1 compile. Somehow, this change causes the build to need Attributes.gen before it's been generated. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@297188 91177308-0d34-0410-b5e6-96231b3b80d8
